WARNING! You really shouldn't use the <center></center> tags once you understand HTML and CSS (which we'll explain a little later). However, since you're just starting to learn HTML, go ahead and use them.

You can make words bold or strong:

<strong>Woo-Hoo!</strong> I'm learning HTML!

Notice that I placed the start bold tag, <strong>, just before the word that I wanted to make bold, as well as placing the end bold tag, </strong>, right after the word I wanted to make bold. This way I am giving specific instructions to the web browser, telling where to start making things bold and where to end. If I had forgotten to put the </strong> tag, it would have totally changed the display in the web browser. Check it out:

<strong>Woo-Hoo! I'm learning HTML!

You can make words italicized or emphasized:

Woo-Hoo! I'm <em> learning </em> HTML!

You can even use tags in combination. Want something bold and in italics? No problem:

<html>

<head>

<title> Learning HTML </title>

</head>

<body>

<strong><em>Woo-Hoo! I'm learning HTML!</em></strong>

</body>

</html>
